Once I get my car washed and before I dry it, I always drive it around the block which is not that far maybe 1 min to get the water off my wheels. Is it that bad for the paint? Am I throwing any dirt on the paint and then drying it rubbing the dirt all in my paint?

The only reason Steve is cause it blows some water of my black paint to decrease water spots but I started back in July using this meguiars quick retailer called shine as you dry or something you spray it when your car is wet and dry it and it does really good and normally I have no water spots.

x2. i just started using an electric leaf blower i bought on amazon for $30. it works like a charm and i even use it for it's intended purpose of clearing the garage of leaves after using it to dry off my car

... Am I throwing any dirt on the paint and then drying it rubbing the dirt all in my paint?

THAT'S EXACTLY WHAT YOU ARE DOING.

Every drop of water on your car has just become a dirt magnet. Add your towel and you are now making sandpaper on your paint. WAY WRONG ANSWER. You should NEVER drive a car dry unless you plan to wash it again later and you also do not plan to wipe on it in any fashion.

By the way, I no longer use a leaf blower to dry my car. I now use the Air Force Master Blaster.
